I bought a Canon HF R600 camcorder because I couldn't accept the prop sync I have seen on GoPro videos caused by the "rolling shutter." Problem is the all the camcorders use this shutter to get better videos so I had the same affect on my Canon. Another reason I bought the canon besides it being less than half the cost is that it has a mike input and head phone output along with an HDMI output. That way I can record the air-to-air conversations.

I resolved the prop sync issue the same way the GoPro does. I bought a screw on HD8 filter for about $35.

Can't see any of the prop unless you are facing into the sun which caused the shutter to speed up. Still it is not near as bad as seeing several prop blades through the wind screen without the filter. I am well satisfied with this camcorder and will use it to document my 1st flight from SoCal to OSH this July.
